Problems solved by technology

While this is a common technique for dispensing a variety of fragrances, typically it has been less successful when dispensing certain particularly desirable pest control materials.
However, it is difficult to design such devices to work over a four hour, six hour or even longer period (four to six hours being a typical period for a dinner party or picnic) while consistently distributing enough chemical to be effective in a large area throughout that period.
However, such systems required structures to generate, store, and / or accommodate electrical power, which increases the cost of the device.

Embodiment Construction

[0029]FIGS. 1-3 shows a device in the form of a candle dispenser 10 for dispensing air treatment chemical. The candle dispenser 10 includes a housing 14, a base 18, and an upper caddy 22. With reference to FIG. 2, the upper caddy 22 holds a heat source in the form of a candle 26 and a substrate 30. As shown in FIG. 1B the housing 14 can alternatively be a transparent housing.

[0030]As shown in FIGS. 4 and 5, the housing 14 is generally sleeve-shaped and may be referred to as a shade or a chimney. The housing 14 includes a substantially hyperbolic shaped side wall 34 with a curvature and a base engaging structure in the form of four tabs 38. The side wall 34 defines an interior cavity 42 with an open top, an air inlet in the form of two bottom vents 46, and a caddy mounting feature in the form of two caddy recesses 50. The housing 14 may be made of glass or another heat-resistant transparent or translucent material, such as a plastic. A translucent housing 14 would ornamentally hide p...

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application is a division of U.S. patent application Ser. No. 14 / 289,761, filed on May 29, 2014, which is hereby incorporated by reference in its entirety.STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH / DEVELOPMENT[0002]Not applicableBACKGROUND OF THE INVENTION[0003]The present invention relates to devices that dispense air treatment chemicals (“actives”) from a substrate using the heat of a candle to drive the dispensing. More particularly, the invention relates to such devices that dispense the active over a prolonged period in a relatively consistent manner that provides effective coverage throughout an area such as an outdoor patio.[0004]A variety of devices are known for dispensing volatilizable air treatment chemicals such as pest control materials (e.g., insecticides, insect repellants, or insect growth control regulators), air scents or deodorizers (e.g., masks), allergen control ingredients, disinfectants, sanitizers or oth...
